2 Safety precautions

The precautions described below are intended to prevent danger or injury to the user and other personnel through safe,
correct use of the product. Use the product only after carefully reading and fully understanding these instructions.

Handling the product without observing the instructions that accompany a "Warning" symbol
may result in serious injury or death.

Handling the product without observing the instructions that accompany a "Caution" symbol

Note

Explanation of graphic symbols

Indicates "prohibited" actions that must not be
performed.

Do not use the product in explosive or corrosive environments, in the presence of ammable gases, locations subjected to splashing



water, or near combustibles. Doing so may result in re, electric shock or injury.
Do not transport, install the product, perform connections or inspections when the power is on. Always turn o the power before

Do not forcibly bend, pull or pinch the cable. Doing so may result in re or electric shock.



Do not touch the connector of the speed controller immediately after the power is turned o (for a period of 1 minute). Doing so may



result in electric shock.
Do not disassemble or modify the motor and speed controller. Doing so may result in electric shock or injury.



Only qualied and educated personnel should be allowed to perform installation, connection, operation and inspection/



troubleshooting of the product. Handling by unqualied and uneducated personnel may result in re, electric shock or injury.
Install the speed controller in an enclosure. Failure to do so may result in electric shock or injury.



For the AC power supply voltage of the speed controller, use the same power supply voltage as the motor specication. Failure to do so



may result in re or damage to equipment.
The speed controller has no built-in fuse for overcurrent protection. Be sure to connect a device for fuse in the AC power supply line.



Failure to do so may result in re.
Securely connect and ground in accordance with the section for connection. Failure to do so may result in re or electric shock.



Be sure to observe the specied cable sizes. Failure to do so may result in re.



Insulate the connection terminals of the included capacitor using the included capacitor cap. Accidental contact may result in electric shock.

Do not use the motor and speed controller beyond their specications. Doing so may result in electric shock, injury or damage to equipment.



Do not carry the motor by holding the motor output shaft or motor lead wires. Doing so may cause injury.



Keep the area around the motor and speed controller free of combustible materials. Failure to do so may result in re or a skin burn(s).



Do not leave anything around the motor and speed controller that would obstruct ventilation. Doing so may result in damage to equipment.



Do not wire the electromagnetic contactor or power relay between the motor and speed controller. To switch the rotation direction



using the electromagnetic contactor may cause damage to equipment.
Do not touch the rotating part (output shaft) while operating the motor. Doing so may cause injury.



Do not use the product in vertical drive (elevating application). Doing so may result in injury or damage to equipment.



If an alarm of the speed controller is generated, remove the cause before resetting the alarm. Failure to do so may result in injury or



damage to equipment.
Securely install the motor and speed controller to the mounting plate and DIN rail respectively. Inappropriate installation may cause



the motor and speed controller to drop, resulting in injury or equipment damage.
Use a motor and speed controller only in the specied combination. Failure to do so may result in re.



Provide an emergency-stop device or emergency-stop circuit external to the equipment so that the entire equipment will operate



safely in the event of a system failure or malfunction. Failure to do so may result in injury.
Be sure to ground the motor and speed controller to prevent them from being damaged by static electricity. Failure to do so may result



in damage to equipment.
If abnormal conditions occurred, stop the operation immediately and turn o the speed controller power. Failure to do so may result in



re, electrical shock or injury.
Conduct the insulation resistance measurement or dielectric strength test separately on the motor and speed controller. Conducting



while the motor and speed controller are connected may result in damage to equipment.
The motor surface temperature may exceed 70 °C (158 °F) even under normal operating conditions. If the operator is



allowed to approach the motor in operation, attach a warning label in a conspicuous position as shown in the gure.
Failure to do so may result in a skin burn(s).

4 Installation

This chapter explains the installation location and installation methods.

4.1 Installation location

The speed controller described in this manual has been designed and manufactured to be incorporated in general
industrial equipment.
Install it in a well-ventilated location that provides easy access for inspection.
The location must also satisfy the following conditions:

Indoors



Operating ambient temperature: 0 to +50 °C [+32 to 122 °F] (non-freezing)



Operating ambient humidity 85% or less (non-condensing)



Area that is free of explosive atmosphere or toxic gas (such as sulfuric gas) or liquid



Area not stored combustible materials



Area not exposed to direct sun



Area free of excessive amount of dust, iron particles or the like



Area not subject to splashing water (rain, water droplets), oil (oil droplets) or other liquids



Area free of excessive salt



Area not subject to continuous vibration or excessive shocks



Area free of excessive electromagnetic noise (from welders, power machinery, etc.)



Area free of radioactive materials, magnetic elds or vacuum



Altitude Up to 1000 m (3300 ft.) above sea level



4.2 Installing the speed controller

The speed controller is designed so that heat is dissipated via air convection.
Provide spaces so that the speed controller can be ventilated well through its top and bottom vent holes.

Installation direction



When installing the speed controller, provide a clearance of at least 25 mm (0.98 in.) in the vertical direction between the
speed controller and enclosure or other equipment within the enclosure.
When installing two or more speed controllers in parallel, it is possible to install them closely in the horizontal direction.

25 mm (0.98 in.)
or more

Installation method

Mounting hole



Mounting to DIN rail

Use a DIN rail 35 mm (1.38 in.) wide to mount the speed
controller.

Hook

Pull down the DIN lever of the speed controller until it
locks, and push in the speed controller with hanging the
hook at the rear to the DIN rail, and then lift the DIN lever.
After installation, secure the both sides of the speed

DIN rail

controller with the end plate that the customer provides.

DIN lever

Removing from DIN rail

Pull the DIN lever down until it locks using a at tip
screwdriver, and lift the bottom of the speed controller to
remove it from the rail.
Use force of about 10 to 20 N (2.2 to 4.5 lb.) to pull the DIN
lever down.
Excessive force may damage the DIN lever.

Installing with screws

Install the speed controller through the mounting holes using two screws (M4: not included).
Tightening torque: 0.7 N·m (6.1 lb-in)
Use screws and washers, which sizes are Ø10 mm (0.39 in.) or less, to secure the speed controller.

Installation

End plate

When installing with screws, pull up and down the upper
and lower levers on the rear side of the speed controller
respectively before doing so.

4.3 Installing the capacitor

Before mounting the provided capacitor, check that the capacitor’s
capacitance matches that stated on the motor’s name plate.
Install the capacitor securely using M4 screw (not included).

Do not let the screw tightening torque exceed 1 N·m (8.8 lb-in) to prevent damage to the mounting foot.

Note



Install the capacitor apart from the motor. If it is located closer, the capacitor life may be shortened due to
